AMD Sensitivity File

The device is shipped with a default, pre-installed AMD Sensitivity file for its Answering Machine Detection (AMD) feature. This file includes the detection algorithms for detecting whether a human or answering machine has answered the call, and is based on North American English. In most cases, the detection algorithms in this file suffice even when your deployment is in a region where a language other than English is spoken. However, if you wish to replace the default file with a different AMD Sensitivity file containing customized detection algorithms, please contact the sales representative of your purchased device for more information.

The AMD Sensitivity file is created in .xml format and then converted to a binary .dat file that can be installed on the device. The XML-to-binary format conversion can be done using AudioCodes DConvert utility. For more information on using this utility, refer to DConvert Utility User's Guide.

Only one AMD Sensitivity file can be installed on the device. To install a new AMD Sensitivity file, use one of the following methods:

■

Web interface: Auxiliary Files page - see Loading Auxiliary Files.

■

TFTP during initialization: Configure the [AMDSensitivityFileName] parameter, and then copy the AMD Sensitivity file to the TFTP directory.

■

Automatic Update feature: Configure the [AMDSensitivityFileUrl] parameter through ini file. For more information, see Automatic Update Mechanism.
